A. Because of the nature of its construction, bias ply tires have a circumference (rollout) that varies from tire to tire. At the factory the tire is inflated to a set pressure and the rollout is then measured. The rollout will help in deciding which tire best suits your needs.
A. We recommend dynamic balance in high-speed applications, however, because the tire changes shape as you race, no method can guarantee balance.
A: ONLY trained professionals with proper tools should mount and dismount the drag slick. Failure to do so may cause tire damage that could lead to a tire failure and result in an accident, injury or death. Always check the tire and rim prior to mounting as damage could have occurred during shipping and storage. NEVER exceed tire air pressure of 35 PSI in the drive slick or 40 PSI in the free rolling.
A. No. However, a new set should always be mounted as follows:
After a few passes the tires can be swapped side-to-side. Rotating every few passes will clean the tread surface of the feathering and balling up of the rubber on the surface.
A. No, the tires are designed solely for racing purposes and are not tested or labeled to meet FMVSS 109 or ECE30 Safety Standards for use on the street. IT IS ILLEGAL TO USE THESE TIRES ON PUBLIC ROADS.
A. Currently we offer only one compound for each size. We have found that this compound works in hot and cold race conditions.
A. The tire at ambient temperature is not an indication of how well the compound will work. This is one of the reasons to do a burn out. Building heat in the tread will soften the rubber for maximum traction.
